Save-All-Javascript-Function.JPG

I have a Telerik Grid with paging.

I want to Select All the rows in the Radgrid from a checkbox given in Header template of the grid from Client Side function

I am attaching my aspx code for your reference ,along will I am also attaching the javascript code that I am using currently.

But this code Selects all the rows of the same page and I want to select all the rows across all the pages in the grid by

Checking the Checkbox given in Header Template.

Hello,

please Check below code snippet.

bool flag = false;

if (RadGrid1.MasterTableView.GetItems(GridItemType.Header).Count() > 0)

{

GridHeaderItem hItem = RadGrid1.MasterTableView.GetItems(GridItemType.Header)[0] as GridHeaderItem;

flag = (hItem.FindControl("AllCheckBox1") as CheckBox).Checked;

}

RadGrid1.AllowPaging = false;

RadGrid1.Rebind();

foreach (GridDataItem item in RadGrid1.MasterTableView.Items)

{

item.Selected = flag;

}

// you can access your all checked items here

RadGrid1.AllowPaging = true;

RadGrid1.Rebind();

Thanks,
